The analysis of the gravitational data from 2004 and 2011 consistently shows regular phase reversal at intervals of around 50 hours. The four-leaf directional pattern rotates in 200 hours westwards around the N-S axis of the earth. The supposed "anomalous splitting" of 3S2 is a measurement error, caused by wrongly chosen parameters of the Fourier transformation.
Sensible use of tillage requires knowledge about different aspects of soil crumbling.
Decisions of best management practices must be based on complex considerations
regarding e.g. effective tractor use, long-term soil health, etc. Research on soil carbon
fluxes in tilled soils is an area of investigation which has received much attention
recently, but ideally it should be approached in a combined bio-physical manner. We
conducted studies on respiration from freshly fragmented clay soil in different aggregate
size fractions with help of a multi-channel respirometer. The fragmented soil was
characterized in terms of different soil carbon pools. The physical fragmentation itself
was characterized in a manner that should be relevant to the three existing ways of
relating use of a specific tool configuration to physical outcome of the operation, namely
soil mechanical tillage experiments in situ, tests in soil bins and computational soil
mechanics. Linear regressions showed that higher specific aggregate surface area, more
free organic C per dry soil and more occluded C per dry soil led to higher soil respiration

An exceptionally simple model of ball lightning is proposed that describes it as a highly charged sphere of hot, conductive, air
surrounded by colder air. This conductive sphere possesses a net excess of charge. This charge will create a corona discharge that
will heat the surrounding air thus maintaining the temperature of the ball itself. Numerical simulations are presented which give
results that would appear to agree with what many witnesses have reported. It is argued that such spheres are likely positively
